Yes, good idea !

Of I replace it with a green-line-effect propeler ?

But afther the competition, because I think we can't do any change now no ? 

Really cool, except the propeller. You might just remove it, the green lines are enough I think, and it would draw attention back to the central red thing.

Agreed about the propeller shading. Everything else looks so dark and boding. Like it's part of some evil machine. Good work.

 I think the shading on the propellor could be better, but otherwise really cool!

 So many great entries this week. Gonna be hard to vote.

Ok, I was doing this either before I red the  revision message,

but I ve lost a random color. :(

Bah, it wasn't a very visible one.

Resubmitted.
 

Some things are to redo, now also, but so.

Then why not place it on a black background?

Transparency - Required. However, the transparency must only be used outside of your chosen shape.

Anyway, resubmit once you've corrected this.

Awesome, great work.
